#2 Ryan Newman.
Lets be honest with this one. Despite this entry on the list mostly be speculation, there are a few factors that create the possibility of Newman actually stepping away from Richard Childress Racing at the end of the season. The first is the fact that Newman signed what is described by several sites a multi year deal, which could mean the contract is up at the end of the season.
Another huge factor is that Newman is 40 years old, which means RCR could be wanting to replace him with some new blood. The last factor is his performance record, which has been mediocre at best over the last couple of years and consists of only three top-tens this season.
He is also on the verge of losing his spot in the playoffs given the fact that he currently sits in 16th place.
